Since every dynamic IP on the Internet is on the PBL list (and some static too), and since not everyone is configured to authenticate when sending mail (e.g. Comcast does not require SMTP authentication on their server for mail sent *from Comcast's network*, and there are millions of people on Comcast), aren't you setting yourself up for guaranteed false positives? And not necessarily a few, either, particularly if you get mail from non-business users. XBL can block all sorts of people too, according to their FAQ, though it doesn't sound as bad. It seems like the only safe one of Spamhaus's is the SBL, which deals with known entities. Spamcop.net's doesn't exactly comfort either, with its statement "The SCBL is aggressive and often errs on the side of blocking mail." I would think that they'd want to err on the opposite side, but maybe that's just me, with a reflex response to hearing from people who aren't getting their mail. Finally, zen.spamhaus.org carries this warning, which I don't full understand beyond it being yet another thing to worry about: "Because ZEN includes the XBL and PBL lists, do not use ZEN on smarthosts or SMTP AUTH outbound servers for your own customers (or you risk blocking your own customers). Do not use ZEN in filters that do any �deep parsing� of Received headers, or for anything other than checking IP addresses that hand off to your mailservers." Am I missing something? |
